Bobby's back on 'Supernatural'!

Castiel returns to Supernatural tonight, and next week will see the return of another familiar face when Bobby (Jim Beaver) takes the lead in a very special episode! Directed by Dean himself, Jensen Ackles, 'Weekend At Bobby's' will see the hunter team up with the returning Sheriff Mills (Kim Rhodes) to tackle a spooky case. On top of that, the demon Crowley (Mark Sheppard) is also back to cause more trouble for Bobby! Check out some new images from episode four below!
